If you need a wall-mounted bedside lamp you can easily hack one together using an Ikea $1.99 Rationell Variera plastic bag dispenser by adding a cheap lamp socket and a piece of translucent plastic from a binder.

Maker blog CoreSince1984 gives detailed instructions and photos, but all that is necessary is to cut a hole in the bottom of the bag dispenser to feed the lamp socket through. After that is done just attach the dispenser to the wall, insert the plastic (an A4 or 8.5" x 11" piece should fit perfectly) to diffuse the light, and plug it in.
